ES430 / ES432 – Lambda modules

The ES430 and ES432 Lambda Modules are capable of withstanding the environmental conditions which are typical for exhaust system installations.

The ES430 and ES432 modules facilitate lambda measurement in combination with the Bosch Lambda Sensors LSU 4.9 (ES430/ES432) and LSU ADV-G (ES432). The modules automatically detect the type of sensor connected and set all necessary parameters.

To provide for reliable measurements, ES430/ES432 operates the connected sensor at constant temperature. Based on the raw sensor signals, ES430/ES432 calculates lambda (λ) values as well as 1/λ, air-fuel ratio (A/F), fuel-air ratio (F/A), and oxygen content (O2) in physical representation. The sampling rate of the signal is in the range of 0.5 Hz and 2 kHz. To feed analog post-processing for example at test beds ES430/ES432 provides an electrically isolated analog output. Sampling rate and analog output are software configurable.

To prevent damage or degradation of the sensor element, ES430/ES432 continues heating the sensor ceramics when the modules enter the stand-by mode by disconnecting the host.

To prevent applying wrong characteristic parameters to a sensor, the sensor type is automatically detected via the sensor cable or the sensor itself (LSU ADV-G).
